The top loading鹤管 is a specialized equipment designed for the loading and unloading of various liquids and liquefied gases at the top, whether in open or closed conditions. It is widely used in the petrochemical industry, oil transportation, and other fields. Below is a detailed introduction to it:
Structural composition
Swivel Fitting: Generally made of alloy steel and stainless steel, precision-machined on CNC machines, featuring an internal double-raceway support structure. It can withstand axial, radial, and torque loads, offering flexible and reliable rotation with no leakage. It is a critical component for the rotational action of the crane boom.
Sealing Cap: The conical sealing cap on the vertical pipe is inserted into the top filling opening of the tanker during loading, ensuring the sealing cap is pressed firmly at the filling opening for a secure seal.
Balancing System: Such as the spring cylinder balancing system, which can be balanced at any point, making alignment operations smooth and reasonable, and convenient for the operator to adjust the crane boom position.
Pipe: Includes liquid-phase pipes and gas-phase pipes. Liquid-phase pipes are used for transporting liquid mediums, while gas-phase pipes are for emptying or connecting gaseous mediums in tank trucks to an oil-gas recovery system. Materials for pipes can be carbon steel, stainless steel, low-temperature steel, etc.
Features
Operational Flexibility: Equipped with multi-section rotating connectors and telescopic arm structures, it offers 360° horizontal rotation and vertical lifting capabilities, accommodating various tanker heights and positions for quick and precise connection.
Safety and Reliability: Equipped with dual-sealed system and anti-static devices, it ensures sealed transmission of volatile substances like benzene and alcohols, reduces VOCs leakage, and simultaneously diverts frictional charges to the grounding system, eliminating the risk of combustion and explosion.
Versatile: Made from high-strength aluminum alloy or stainless steel, it is highly resistant to corrosion and pressure. With modular design, it can meet extreme operating conditions from -196℃ to 300℃. It can also be customized with low-temperature insulation and nitrogen blow-off functions as per customer requirements.
Easy Maintenance: Modular design facilitates component replacement, reducing maintenance costs.
Application Range
Applicable Occasions: Primarily used for tank trucks without bottom unloading hatches, as well as for the top open liquid loading at small and medium-sized oil depots and gas stations.
Applicable Media: Suitable for gasoline, diesel, liquefied gas and other hazardous chemicals, as well as heavy oil, chemical media, etc. For media that are not easily volatile at room temperature, have poor fluidity, high viscosity, or tend to solidify, a heating system can be used.
Main Models and Parameters
AL1401/AL1402 Models: Suitable for gasoline, coal, diesel, liquid chemical media, water coal slurry, etc., for top-loading on vehicles. Applicable pressure range is 0.6MPa to 2.5MPa, design temperature is -19℃ to +110℃, material options include stainless steel, carbon steel lined with PTFE, etc.
AL1403 Model: Suitable for top loading and unloading of finished oils, chemical media, etc. in vehicles. Design pressure ranges from -0.08MPa to 2.5MPa, and design temperature from -50℃ to +110℃.
AL1412 Model: Top-sealed loading arm, suitable for volatile and toxic media. Operating pressure range: 1.0MPa to 2.5MPa. Material options include stainless steel, carbon steel lined with PTFE, etc.
